Test A: Amazon marketplace selling
If a candidate product's incremental recovery could change the route, inspect the exact UPC/ASIN in Seller Central → Catalog → Add Products. Record exact model, variation, condition, restriction text, date, scope, and evidence requested. “Apply to sell” is not approval. Listings guide.
Individual is published at $0.99 per item; Professional at $39.99/month. Subscription-only arithmetic crosses at 41 Amazon units/month, but required features or restricted products can change the choice. Do not buy Professional merely to investigate MCF. Amazon pricing.
Test B: MCF fulfillment
Amazon documents an MCF route for businesses that do not sell on Amazon. MCF-only Supply Chain Portal product records do not need an Amazon-store listing match or brand authorization, but product/safety acceptance still applies. Supply Chain Portal stock cannot fulfill Amazon-store orders. MCF product records.
Q4 caveat: Amazon's 2026 peak period is October 15–January 14, plus a 3.5% fuel/logistics surcharge. The modeled large-standard 1–2 lb rate is $11.35 per order at peak + fuel, before inbound, prep, storage, returns, connector, and exceptions.
MCF pricing.
Tax-interview risk: for a disregarded single-member LLC owned by an individual, IRS guidance generally points to the owner's SSN or owner's EIN on the W-9—not necessarily the LLC bank EIN. Confirm the actual entity/tax facts; AK reviews and certifies the generated form.
